what is value of x in the multi-step equation
22-9x=9x+10
Answer:
x= 2/3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
22−9x=9x+10
22+−9x=9x+10
−9x+22=9x+10
Step 2: Subtract 9x from both sides.
−9x+22−9x=9x+10−9x
−18x+22=10
Step 3: Subtract 22 from both sides.
−18x+22−22=10−22
−18x=−12
Step 4: Divide both sides by -18.
x=2/3
Identify the points which of the following coordinate pairs make the equation x - 9y = 12 true?
Show your reasoning.
1. ( 12, 0 )
2. ( 0, 12 )
3. ( 3, -1 )
4. ( 0, - 4/3 )
Answer:
Step-by-step explanation:
Because in equation x-9y=12
If we put x=12 and y=0 then it satisfy equation. (12)-9(0)=12
So, (12,0) make equation
(3,-1) also make equation
(3)-9(-1)=12
(0,-4/3) also make equation
Because
0-9(-4/3)=12
Only (0,12) is not making
Beacuse
(0)-9(12) is not equal to 12

Dennis stood on a 9 foot ladder to measure the sunflower. How much taller is the tallest sunflower than the ladder?
Answer:
See Explanation
Step-by-step explanation:
Given
[tex]Ladder = 9ft[/tex]
[tex]Tallest\ Sunflower = x[/tex]
Required
How much taller is the tallest
To get this, we simply calculate the difference between the height of the tallest sunflower and the ladder.
i.e.
[tex]Difference = Tallest\ Sunflower - Ladder[/tex]
[tex]Difference = x - 9[/tex]
-----------------------------------------------------------------------------------------------------
If for instance, the tallest is 13ft, then it is 4ft taller.
Because:
[tex]Difference = 13ft - 9ft[/tex]
[tex]Difference = 4ft[/tex]
A rectangular doubles tennis court is (8x - 2) ft long and (4x - 4) ft wide. Which expression represents the perimeter of the tennis court?
A (12x - 6) ft
B. (12x + 6) ft
C (24x - 12) ft
D. (24x + 12) ft
If you can please show the steps
Answer:
C
Step-by-step explanation:
Remark
The easiest way to do this is to add the two givens together and then multiply by two. Why 2? Because the formula is P = 2(L + W)
Givens
L = 8x - 2
W = 4x - 4
Solution
P = 2*(8x - 2 + 4x - 4)
P = 2*(12x - 6)
P = 24x - 12

Find each percent change. Round to the nearest tenth of a percent. State if it is an increase or decrease. From 79 miles to 84 miles
A) 6.3% decrease
B) 5% increase
C) 6% decrease
D) 6.3% increase
Answer:
the answer is d.
Step-by-step explanation:
first, you want to use the formula,
new value - original value
____________________
original value * 100
you see that 84 is the new value and 79 would be the original value. substitute the numbers in. this is a increase since you will get a positive value.
84 - 79
______
79 * 100
now we solve it.
5
__
79 * 100
you can either solve the fraction first then multiply that by 100 or multiply the numerator by 100 first then divide that by 79, each way works.
500
____
79 = approximately 6.3% increase (this is not a exact value, just rounded)
or
5
__
79 = approximately 0.063 (this is not a exact value, just rounded)
0.063 * 100 = 6.3% increase
Two trains on opposite tracks leave the same station at the same time. One train travels at an average speed of 80 kilometres per hour and the other travels at an average speed of 70 kilometres per hour. How long after they leave the station will they be 50 km apart?
Answer:
1/3 hr or 20 min.
Step-by-step explanation:
Call the trains A and B
Remember d = rt
Distance train A travels is 80t
Distance train B travels is 70t
Now, 80t + 70t = 50
150t = 50
t = 50/150 = 1/3 hr or 20 min.

A pack of 5 of board games costs $75.
If there is a direct proportion between the price (y) and number of board games (2), which equation represents the
situation?
A
y = 2
y = 15.2
y = 52
y = 75.00
Answer:
C. y=5x
Step-by-step explanation:
I'm pretty sure that it's y=5x, because it says that y represents the price, and that 2 represents that amount of board games. The price is $75, and the number of board games is 5. So the answer should be y=5x.

Answer:
a. The domain of the function is -3 < x ≤ 5
b. The range of the function is -3 ≤ y < 3
c. The y-intercept is the point (0, 0)
d. The values of 'x' at which f(x) ≥ 0 are;
x = -3, x = 1, x = 5
e. The intervals over which f(x) is decreasing are;
-3 < x ≤ - 1, and 1 ≤ x ≤ 3,
f. The local minimums are;
(-1, -1), and (3, -3)
Step-by-step explanation:
a. The domain of a function is the set of the possible independent variable values
Therefore, the domain of the function is -3 < x ≤ 5
b. The range of a function is the set of the possible values of the dependent variable
Therefore, the range of the function is -3 ≤ y < 3
c. The y-intercept is the point (0, 0)
d. The values of 'x' for which f(x) ≥ 0 are;
x = -3, x = 1, x = 5
The range of values of 'x' where f(x) ≥ 0 are;
-3 < x ≤ - 1.5, 0 ≤ x ≤ 1.5, 4.5 ≤ x ≤ 5
e. f(x) is decreasing over the following intervals;
-3 < x ≤ - 1, and 1 ≤ x ≤ 3,
f. The local minimums are the points that are lowest compared to other nearby points
The local minimums are;
(-1, -1), and (3, -3).

The school orchestra is creating a CD of their last concert. The total cost to make the CD is $300 plus $2.50 per CD. They are selling the CDs for $10 each. How many CDs will they need to sell to make a profit?
Answer:
They need to sell more than 40 CDs to make a profit.
Explanation:
They will make a profit when the sales are higher than the cost and with the information provided, you can write the following inequality:
10x>300+2.5x, where x is the number of CDs sold
Now, you can solve for x:
10x-2.5x>300
7.5x>300
x>300/7.5
x>40
According to this, the answer is that they need to sell more than 40 CDs to make a profit.
A line that passes through the points (-3,5) and (6,10)
Answer:
y = 5/9x + 19/3
Step-by-step explanation:
slope: 10 - 5 / 6 - (-3) = 5/9
point-slope form:
y - 5 = 5/9(x + 3)
y -5 = 5/9x + 4/3
y = 5/9x + 6 1/3
